Electric Single Seat Control Valve
The single-seat control valve is an industrial field execution instrument composed of the control valve body and different electric actuators. It accepts the 4-20mA or pulse signal output by the regulator for closed-loop control, and realizes the control of flow, pressure, temperature, liquid, etc. Automatic control of parameters such as bits, and intelligent electric actuators can be selected to realize digital transmission with DCS, PLC, etc. to form a more intelligent control system.
The power supply voltage of the electric control valve is 220V and 380V, and the flow characteristics of the electric control valve are equal percentage, linear, fast and so on. Compared with the pneumatic control valve, the electric control valve has the advantages of energy saving (only consumes electricity when working), environmental protection (no carbon emission), quick and convenient installation (no need for complicated pneumatic pipelines and air pump workstations), etc. It is widely used in electric power, chemical industry, metallurgy, environmental protection, water treatment, light industry, building materials and other industrial automation systems.
